@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
SHA256:uHkeKkiLSxAIIGmk89BkPqq2zEfXKsiBdYDF3mwvq6A.
Please contact your system administrator.
Add correct host key in ~/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in ~/.ssh/known_hosts:24
ECDSA host key for 10.87.218.183 has changed and you have requested strict checking.
Host key verification failed.

 

报错信息里，写的很清楚了：

Offending ECDSA key in ~/.ssh/known_hosts:24

到known_hosts文件里删掉错误的主机SHA记录重新连接就ok了。

出现这种状况的原因可能是远端机器有所变化，导致的机器码SHA出现变化，校验不通过~

删除掉known_hosts对应ip的行，就可以了。
